Scientific Description
Habit and structure. Thallus to 4 mm tall, rusty brown, with a limited prostrate axis and sparse erect axes. Attachment rhizoids unicellular with digitate ends, occasionally saccate, pit-connected to the pericentral cells of prostrate axes. Prostrate axes to 170 µm diam. [segment L:B 0.3–0.5]. Erect branches 100–160 µm diam. [segment L:B 0.2–0.5], becoming shorter near apices. Axes with 4 pericentral cells, ecorticate. Trichoblasts/scar cells arising at irregular intervals, often in displaced pairs on subsequent segments, but then with 6–8 naked segments.
Reproduction. Spermatangia in cylindrical heads forming as 1 branch of a basal dichotomy of trichoblasts, 140–200 µm long, 50–70 µm diam., lacking a sterile apical cell. Other reproductive structures not observed.
Distribution. Known only from the type locality and a single collection from the northern Kimberley, north-western Australia.
Habitat. epiphytic.
